Friends of Sustainable Grids (FOSG), formerly Friends of the Supergrid, is an international Brussels-based non-profit committed to transforming the way we look at energy grid infrastructure. With an emphasis on the energy transition and a commitment to significantly increasing sustainability, FOSG focuses on: (i) Connecting (all) types of Energy Grids (through roundtables resulting in concept and demand notes, active involvement in stakeholder groups re PCIs, interconnections, etc.) and (ii) Energy Education (to increase public acceptance and inform policy-makers).
